Same Issue Bernadette
Bernadette I'm having the same issue ! Suddenly apple wireless keyboard "e" opens email ,"c" opens calender ,nothing else works ? .I forgot and re-paired it but still the same . I'll turn the kfhd off now and see if that fixes it .Only thing is I'm not sure I even let the kfhd go to sleep ? One minute I was typing happily but I did this clumsy almost dropping the keyboard off my lap type move but caught the keyboard without actually dropping it.Therefore I was actually under the impression that l'd accidentally pressed a magic keyboard combination for some kind of keyboard output mode , I was just trawling the net to find put what I'd done ! So maybe thats not the case !
